lll)

ycitizen ol the United States Be it known that l, donn oireovn a residing at Miltord, in the county of New llaven and State of Connecticut,.have invented certain new and useful improvements in Gas-Burners, 0i

which the following is a specilication, reference being had therein to the accompanying drawings.

i'lhe present invention has relation to burners of a 'type which consume a gaseous fuel and has as one ol its objects, among I other things, to construct an ecient burner.

las

Accordingly, the burner is provided with a multiplicity ol burner tubes orburner units, arranged in positions relatively to each other 'and to baime posts or bande units surrounding the'burner tubes, so that an equalsupply .of

'air is suppliedto each and every llame jet through air passages deiined by. said baos and burner tubes and located in the same plane as the burner and bame posts but in a lane below a combustion space or chamber inclosed by a ange or guard surroundingthe name jeta Another object or the invention 1s to coni struct the burner el as few separable sections v as possible so as 'to facilitate manufacture and assemblage of the burner.

The invention will be hereinafter described and ascertained, and an embodiment thereof isy illustrated inthe accompanying all drawings, wherein:

Figure l is a side elevation of the burner gas supply pipe connected Fig. 2 is a plan view oi the burner; and

1 Fig. 3 is a sectional view taken upon line 3--3 of Fig. 2 looking in the direction of the arrow, and in this ligure the burner is represented as being seated in an opening at the bottom of an oven of which only a fragmentary part is shown. A

The improved burner, as illustrated, is

constructedol three parts, namely, the body4 portion l, the lower `portion orgas distributer 2 and the upper portion or covering member 3. rlhe component parts of the body portion 1 arev relerably all integral therewith and consist of the base d having an opening 5 with its flanged side walls inter- "nally threaded at 6. A plurality or burner tubes or posts 7 extend upwardly from the base l and are arranged by rows in a particular manner and for a purpose, as will be hereinafter set forth. A series of balile posts 8', equally spaced apart, surround the burner tubes or posts 7. 'lhese latter posts '7 have each a central bore 9, preferably reduced at the upper end, and provide a restricted gas passage. also to increase the area of the air passages toward the top, lor

reasons hereinafter stated, the burner tubes.

7 and 'Dame posts' 8. diminish 'preferably in v diameter from the base upward. rlhe gas tid will be equally distributed 'through the passa es 9 in the tubes '7 he upper tir/covering member 3 includes as component integral parts a plate or base 1,6 having a ledge 17 around the louter edge so as' to seat the burner in an opening 18 when theburner is to be inclosed within an oven 19 for example. A vertical dange or flame guard 20 projects upwardly from the base 16 and the shape of the flange or tlame guard is in conformity with the grouping oil the burner tubes l. l`his flange 20 incloses the spaceimmediately above the ,burner tubes on allsides and thus forms a combustion chamber 'for the dame jets. At various points, thedange 20 is o'set at 21 to permit locating of screws 22, whereby the member 3 is secured to the body portionl by engagement of said screws in threaded holes (not shown) Vin the posts 8.- 'llhe 'bottom ol the plate 16 is in the same plane asthe top sur- 'lace of 'the burner tubes 7 and rests on the baffle posts 8.' The plate 16 is provided with 'an opening conforming with the grouping 'of the burner tubes and the outer tubes are partly surrounded by serrations 23 ot the .plate 16 in such a manner that yair coming` from below, between the baille posts 8, is digli lll@

rected to owcompletely and equally around ignition. .By the present means all the air,

necessary for super-combustion is supplied to the flames even when burning as which has not received a pre-mixture o air, and thus the Bunsen principle need not necessarily be employed. Secondly, by means of the present improved means for the distribution of air to the flames, the advantage obtained with thefBunsen burner is enhanced, therefore, the same may be used advantageously in'conjunction with the improvements herein described if desired.

It should be noted that the 'air supply to the'flame jets is indirect, the purpose of the outer posts being to prevent any atmospheric air of the group. All the air which is supplied to theflames is caused to flow first into the passages between the posts and the burner tubes, from which passages the air distributes itself equally and uniformly to all sides of all'thei'flame jets and by means of said posts the air inflow is decreased'in` volume and increased in velocity, distribution even to the innermost flame jets of the group is accomplished, consequently these posts insure an equal distribution of air to all the flame jets of the group.

The tiallv equal distances apart preferably hexagonal in shape and to p rovide an equal air space around each flame jet for the purpose, firstly, .to insure an equal distribution of air'to each flame jet2 burner tubes are spaced at substanand secondly, to prevent the 'products of combustion from returning and. suocating the flames.

The 'group of burner tubes` is surrounded as previously stated by the baille posts'which are preferably spaced around the burner tubes to define the air passages, and these posts preferably increase in thickness from their tops downwardly to form spaces between one post and another ofgreater area at the top 'than at the bottom, the upper or greater area carrying be distributed to supply the outer or greater area of the space occupied by the outer burner tubes and the lower or lesser area carrying the airrequired to be -distributed to supply the inner or lesser area of the- .space occup1ed by the inner burner tubes.

The flanged plate 16 carried bythe baffle posts serves to position' the burner when` used in connection with an oven or inclosed heating chamber and directs theair laterally inward between the posts and the from flowing directly against any of theouter burner tubes or flame jets thus equal to form a group.

the air required to L letame burner tubes, and its inner edgel is spaced at a proper distance from the outer burner tubes to provide the correct air space around theame jets thereof.

I desire. it to be) understood thatV the burner is used for the purposeof heating pots and pans.A The upper portion or covering member 3 may be dispensed with, in which case the complete burner will consist of the body portion 1 and the lower portion or gas, distributer 2.

If desired the covering member 3 may.

be removed and a grid ofthe usual form substituted to support pots and pans. It is obvious that modifications may be made in the construction as described hereinbefore without departing from the spirit of the invention defined in the appended claimsfor example, the groupingA or arrangement of the burner unitsmay be in some form other than hexagonal in s lape. ,Furthermorm it will be understood, that the various partsv thereof may be castli] integral with each other if desired wit lessening the efficiency of the burner.1
